SPP allows you to failover to a replica appliance by promoting it to be the new primary.
NOTE: You can promote a replica to be the new primary anytime the cluster has consensus (that is, the majority of the cluster nodes are online and able to communicate). If you have a quorum failure (that is, the majority of the cluster members do not achieve consensus), you must perform a cluster reset instead. For more information, see Resetting a cluster that has lost consensus.
To promote a replica to be the new primary in a cluster
- log in to a healthy cluster member as an Appliance Administrator.
- Go to Cluster Management:
web client: Navigate to
Cluster > Cluster Management.
- In the cluster view (left pane), select the replica node that is to become the new primary.
- Click
Failover.
-
In the Failover confirmation dialog, enter the word Failover and click OK to proceed.
During the failover operation, all of the appliances in the cluster are placed in Maintenance mode.
Once the failover operation completes, the selected replica appliance appears as the primary with a state of online. All other appliances (including the "old" primary) in the cluster appear as replicas with a state of online.
